Persist Memo and Categories for Pending Transactions
It appears that Mint deletes any Pending transactions after they clear, and enters a New cleared transaction. The result is the loss of any memos, categories and payee name that were applied to the pending transaction.
With no ability to split Pending transactions, the memo is the only way to add any details to a pending transaction. Since Mint clears the memo on clearing, it's a pretty useless feature to allow entry of memos on Pending transactions.
It would be extremely helpful if Mint would copy over the memos of Pending transactions to the matching Cleared transactions. Since cleared transactions don't have any memos, I would think this is a pretty easy one-way copy to do programmatically.
Even better would be if Mint could keep the Category and Payee name of the Pending transaction, rather than replacing it with whatever Mint decides.
